1973 LMC Possibility Of DD-"Adam's Apple"?

On CCF, all Lincoln Cents are considered Modern Coins, so I moved your post to the appropriate section for the proper attention.

Something are just part of the design.

On your images the light is glaring and hiding what you want us to see. Try rotating the coin to allow the light to fall over the area you want to show. Shining a spotlight on something just show as a white glow on those areas.
Note on the the following images.
The one on the top has the light coming from the opposite direction. Note how the light falls over the devices allowing light and shadows. The lower image is the light is in the opposite direction, but it is not so strong it over powers the image. Also using something to diffuse can cut glare. Making a curtain with a plastic grocery bag, filtering the light through sheets of paper. This will cut the glare and allow us to see what you are seeing.

Thanks, E&V. Thanks, Coop. I will try to follow your instructions, Coop. Thanks for the reminder. Hmmmm, forgot to use the curtains....retake pictures, the student did not pass...Lol.
